Eight installation considerations for refrigeration compressor units

Eight installation considerations for refrigeration compressor units

my country's cold storage has entered a stage of explosive growth. The industry is developing very rapidly, but the structure is not very reasonable. Domestic cold chain logistics parks have begun to show surplus, and many cold storage resources are idle. A large number of construction will inevitably further aggravate overcapacity and market competition. The construction boom of cold chain logistics parks urgently needs to be cooled down, and investment construction should become more rational. The government should issue corresponding policies for effective and reasonable guidance, and the industry must change its mindset of focusing on construction and neglecting operation. The editor of okmarts.com introduces you to eight installation considerations for refrigeration compressor units:

　　 1. The closer the cold storage compressor is to the evaporator, the better. It is mainly easy to maintain and has better heat dissipation. If you install it outdoors, you should pay attention to rain. The four corners of the mainframe should be installed with shock-proof gaskets. The horizontal installation is firm and safe to avoid being touched.

2. Radiator installation The closer the radiator installation position is to the host, the better. It is best to place the radiator in the upper position. The radiator installation position has the best heat dissipation environment. The air inlet should not face the air outlet of other equipment, especially oily gas. It should not be short-circuited or facing other windows and equipment, should be 2 meters above the ground, and the installation level should be firm.

　　3. Copper pipe discharge. All copper pipes must be separately worn with insulated pipes and the wires in the same direction should be wrapped together with air-conditioning ties. Try to use straight pipes and fix them in sections. The joints of the insulated pipes and the insulated pipes should be tightly sealed with electrical tape.

　　 Fourth, wire discharge All wires must be tied up with air-conditioning ties, but should be protected by corrugated hoses or wire troughs. The temperature display wires should not be close to the wires as much as possible.

5. Refrigeration system connection. Because the condenser and evaporator of the main engine are pressure-sealed in the factory, there should be pressure when opening the seal, and it can be checked for leaks. The copper pipes should have dust sealing measures at both ends, and pay attention to them during construction. Seal at any time to prevent dust from entering the pipe, condenser→host→evaporator, copper pipe connection by welding method, the interface is firm and beautiful.

　　 VI. Electrical wire performance configuration The wire diameter meets the requirements, the joint is firm, and the pipe needs to be protected, so it can’t be saved, and the power connection is correct. The wire enters the evaporator junction box hole and needs to be sealed with silica gel. If the lamp is connected to 36V or higher, a grounding wire is required. The power supply in the main cabinet needs a three-phase five-wire system, which must be reliably grounded.

7. Temperature control probe installation The probe and the temperature display probe go through the return air port of the evaporator in the warehouse together, and are suspended. The defrost temperature control is also fixed on the top plate. The probe is also perforated into the return air port of the evaporator in the warehouse, and the probe is inserted into the fin In the middle, the temperature control and defrosting temperature control are fixed at the back corner of the evaporator in the warehouse, and all wiring points are sealed.

　　 8. Do not install the balance window on the conspicuous place and the vertical board of the air outlet. The height is 200mm from the upper part of the vertical board.
